Serious Crime Unit 1

Chapter 917 The Second Dead (2)
"We are separated by mountains. How can I guide your work? Let's talk about it when we meet." Jiang Yiming put down the phone and asked Zhou Ting and Lu Yingying to go to the Jiangbei District Traffic Police Brigade. So, the three of them drove towards the Traffic Police Brigade.

After arriving at the traffic police brigade, after some pleasantries, Hu Xin handed the file to Jiang Yiming and then took them to see Wu Shou's BMW.The BMW was placed in the parking lot of the traffic police brigade. The parking lot was built with a huge shed. It was mainly protected from wind and sun, and the evidence would be washed away by rain.

The car had been severely damaged, the left front door had fallen off, the roof had collapsed, and it was crushed like a deflated rubber ball.Lu Yingying walked to the car and looked at it and said: "Captain Jiang, we'd better tow the car back to the Criminal Investigation Team. Xiaorou and I will conduct a thorough inspection of the car. I suspect that the car's microcomputer system has been hacked, so it will cause the car to malfunction." stalled on the railroad.”

Jiang Yiming nodded, turned around and asked Hu Xin: "Captain Hu, we have to tow this car back to the criminal investigation team. Is it convenient for you?"

"Of course it's convenient. A BMW car has excellent performance, but the motor stalls at a critical moment. It is indeed a suspicious thing. When I was inspecting the scene, I had such doubts in my mind. Now that you are here, you can give the car a thorough inspection." After checking, hopefully we can come to a correct conclusion, otherwise Wu Chao would have died unjustly."

"Can you help call a tow truck and tow the car back to our criminal investigation team?"

"No problem. I'll call the tow truck driver and ask him to help tow the car to your criminal investigation team." After saying that, he took out his mobile phone and called the tow truck driver. The driver promised to come.After a while, the driver came. He drove the trailer in front of the BMW and towed the car away.

On the afternoon of the next day, Lu Yingying came to Jiang Yiming's office and said to Jiang Yiming: "Team Jiang, after careful inspection by Xiaorou and I, we found that the microcomputer system of Wu's car was hacked, so the hacker took control of the entire car. When Wu The moment Shuai's car arrived on the railway, the hacker used the computer to remotely turn off the car's motor and windows, so that Wu Shu could not escape, and watched helplessly as he was hit by the train. Poor Wu Shu, before his death I don’t know how desperate it is!”

"Sure enough, it's a murder! Is the firewall level of the BMW microcomputer system high?"

"A second-level firewall cannot be invaded by ordinary hackers. There are no more than 1000 hackers in our city who can hack into BMW computers."

“Can you find the hacker’s IP address?”

"Unable to query, hacker used wave login."

"What is a wave login?"

"The wave login is: IP1 sends an email to IPN, and many proxy IPs are used in the middle. For example, 1 is regarded as the person who sent the email, and N is regarded as the person who receives the email. From 1 to N, it includes 2, 3, 4, 5, 6, 7, 8, 9, etc., the 2, 3, 4, 5, 6, 7, 8, 9 in the middle are all proxy IPs. These proxy IPs can be from China, the United States, Japan, India, etc. The IP address of the country. If N wants to check 1, he must first check 9, then 8, then 7. And so on, but they have to communicate with each country. It is very cumbersome to check the IP between countries. Wait until the IP of 1 is found. After the address, it has already been a matter of years and months, and we don’t have the time and energy. Remember I have popularized science with you before."

"I forgot...then the hacker should be near the scene, right?"

"Yes, he must see Wu Shou's car drive onto the railway with his own eyes, and he must calculate the time so that he can press the execute button on the computer within the first two to three minutes before the train arrives, and then control the entire car. He cannot let Wu Shou take over. There is a lot of reaction time, because if Wu Shou calls for help for a long time, people outside the car can use rocks to break open the window and rescue Wu Shou. If so, the hacker's murder will not be successful."

"Do you think it was Shenqi who did it?" Only Lu Yingying and Jiang Yiming knew Shenqi's secret.

"Shenqi? If you don't tell me, I have already forgotten. It shouldn't be the case. Shenqi uses an encrypted IP address to send us emails. He will not use a wave-like login IP address because it is more troublesome to use a wave-like login IP address. Encrypted IP addresses are easier. Of course, in order to confuse us, Shenqi may also use wave-like login IP addresses."

"The murderer is near the crime scene, so he should choose a commanding position to observe the driving conditions of Wu Shou's car, otherwise he will not be able to do it, and the scene is surrounded by surveillance cameras. Now almost every house has surveillance cameras installed. Device, right? Can I find the murderer from the surveillance video?"

"This method is too stupid and the workload is too much. If the murderer is standing 500 meters away and committing the crime, we have to collect all surveillance videos within a diameter of 1000 meters. Think about it, by the time we find the suspect , what year and month is it? However, since there are no clues at present, we might as well give it a try. If we are lucky, we may be able to find clues soon. "

"There is another clue that can be investigated. The murderer should have followed Wu Shou all the way. Otherwise, how would he know where Wu Shou was going?" Jiang Yiming said.

"Captain Jiang, what you said makes sense. We will review all the surveillance videos on Wu Shou's driving route. Since there is a specific time, the workload of reviewing surveillance videos is not large. I think we will find out soon. Suspect, but I think the murderer is an extremely cunning person, and he will not leave us any clues easily." Lu Yingying answered.

"I think the murderer is guarding near the scene. It is unlikely that he will wait for Wu Shou to pass the railway. There are too many roads to Beishi. How can the murderer be sure that Wu Shou will pass by the checkpoint on Leizhou Road?" "I think he should go first. Ask Chen Yihao and see what she says, and then ask Wu Shou's parents, I think someone must have revealed Wu Shou's whereabouts to the murderer."

"You're right, but it's also possible that Wu Shou told others that he was going to meet Chen Yihao on Saturday."

Jiang Yiming asked Lu Yingying to review the surveillance video of Wu Shou's driving route. Lu Yingying had already seen the driving recorder of Wu Shou's car and knew his driving route, so it was not difficult to do this job.

Jiang Yiming and Zhou Ting went to Wu Guosong first. When Wu Guosong saw them, he said with a dark face: "My son is dead, why don't you let him go? Even if he is a murderer, the law stipulates that the deceased will no longer be held accountable." ”

Wu Guosong's hair was messy, and his eyes showed extreme sadness and despair. He was very haggard, like autumn grass beaten by frost. Both of his sons were dead. It was difficult for others to feel like a white-haired person giving a black-haired person a gift. Understood.Jiang Yiming had seen too many such scenes and didn't care about Wu Guosong's anger.

"Mr. Wu, we can understand your mood. We have seen too many unfortunate people like you. We are not here today to hold Wu Shou accountable, but to learn about another case from you. I can understand I can tell you that your son did not die in an accident, but in a murder!" Jiang Yiming said softly.

"What? Murder? How is this possible? The traffic police brigade investigated the scene and determined that my son died in a traffic accident. Why do you think it was murder? Who is so cruel to take away my only son?" He opened his big eyes, Incredible look.

"Wu Shou's BMW microcomputer system was hacked by a murderer. The murderer took control of the entire car, causing the car's motor to stall at the railway stop and the windows to be closed. Wu Shou tried hard to knock on the car window, but could not open it. At this time, the train Already here, Wu Chao's car was hit by a train outside the railway, causing his death on the spot."

"Who did this? If I catch him, I will skin him alive!" He said through gritted teeth.

"We are investigating. As long as we are given time, we will definitely bring the murderer to justice. In order to catch the murderer as soon as possible, I need your cooperation."

"How could this happen...my son...son..." He murmured, not answering the question. It seemed that his mind had been disrupted by the sudden news.

"Please forgive me... Is your son's girlfriend named Chen Yihao?" Jiang Yiming got Wu Shou's mobile phone from the traffic police brigade. Lu Yingying cracked the password of the mobile phone, and the last person who called Wu Shou was Chen Yihao and Wu Shou often posted intimate photos with Chen Yihao in WeChat Moments. Therefore, Jiang Yiming and others thought that Wu Shou was going to see Chen Yihao that day.

"Yes, her name is Chen Yihao. She is a good girl. We all agree that they are together... Could it be that she... is she the murderer?" Wu Guosong said in a daze.

"Don't think too much. I need to conduct an in-depth investigation to bring the murderer to justice... We just want to talk to her about her and Wu Shou's situation. By the way, we want to tell you that Wu Shou died of murder."

"As long as you arrest the murderer, I am willing to pay 500 yuan to your criminal investigation team...Tomorrow, yes, tomorrow, can you find the murderer?"

"This is impossible. The process of solving crimes is a slow and difficult one. Some cases that have been accumulated for decades have not yet been solved... How is the relationship between Wu Shou and Chen Yihao?"

"Of course, they are planning to get engaged during the Golden Week of October 10 this year, and then travel to Thailand. I will pay for it. Unfortunately...my son, you are so unfortunate..." After saying this, he burst into tears and couldn't help himself.

Jiang Yiming was silent and waited for a while. After watching Wu Guosong calm down, he asked: "Does Wu Shou have any enemies, or has he offended anyone?"

"No, my son is a very good people's teacher and has all the ethics of a teacher. He will not offend anyone." He looked a little sullen, thinking that Jiang Yiming's words were blasphemous to Wu Shou.
